Low Voltage Multifunctional LED Controller / DMX Decoder Specification High Power DMX Decoder & Driver Meets DMX 512/1990 Protocol LT-300 can drive up to 8A current on each channel Capable of driving many kinds of RGB LED lamps and luminaries
INTRODUCTION LT-300 is a multifunctional full-color controller/decoder. With advanced micro processor technology, it converts the widely used DMX512/1990 signal to analog signal. LT-303 also has 34 different pre-programmed color pattern choices, each of the RGB LED has 0-100 regulation levels, users can change LED luminous colors, LED hues and LED brightness according to their needs randomly and can provide as many as 16 millions of light colors. It also contains a DMX512 decoder (three channels) that sends digital controlling signals to produce different color changing patterns. With integrated LCD screen, users can set up various operating parameters easily. The controller has basic power driver modules inside not only can meet the needs of general controlling power, but can be connected to LT-390 to have unlimited expansion power, and can control all LED synchronous products. This compact decoder connects to light console and analog device, RGB LED luminaries allowing lighting designers to create endless possibilities of light shows FEATURES Meets DMX512/1990 protocols. 256-level brightness, full-color control 3 output channels Can drive up to 8A current on each channel Low Input Voltage: DC12V/DC24V Can set the DMX addresses freely LCD screen for easy programming Modular design, can be combined with LED luminaries neatly Over 30 pre-programmed patterns for plug and play solution.

WIRING CONNECTION INSTRUCTIONS WARNING: Do not connect controller directly to 110/220VAC mains voltage. Follow directions in this user manual to prevent damage to controller and to avoid any accident INPUT Terminals DC+ : Connect to +12V or +24V DC voltage DC- : Connect to -12V or -24V NOTE: Output voltage is equal to Input voltage applied! OUTPUT Terminals COM: Connect to common wire of LED anode terminal (DC+) RED: Connect to red LED wire GREEN: Connect to green LED wire BLUE: Connect to blue LED wire NOTE: Controller is for common anode connection INSTALLATION NOTES 1. Avoid placing the controller near lighting strike location, strong magnetic and high voltage area. 2. The controller should be installed indoors. If controller has to be placed outdoor, make sure it is covered in waterproof box 3. Make sure of the right connection to avoid burning the fuse due short circuit. 4. Controller is for common anode LED connection
